Media Encoder CS6 Not using all CPU Cores or RAM

Jun 18, 2012 6:18 PM

I'm currently exporting a 90 second video (using the Vimeo HD 1080p preset), and it is taking about 30 minutes. This is extremely strange as I have an i7-990x OC'ed @4.5, 12GB RAM, SSD, etc.


I looked at Performance tab in Windows Task Manager, and saw 4 threads were not being used at all, only 20-25% of the CPU was in use, and only 6GB out of the 9GB I specified was being used.


Why isn't Media Encoder making full use of my CPU and RAM?

    It'll use whatever it needs.  If it didn't use all resources, then it doesn't need them all.  Possibly because of a bottleneck somewhere else, or a third party effect that isn't very well multithreaded, etc.

    I'm having the same problem. But even worst.


    For the test, I take a 10 min .mov or mp4 file, simply modify the "scale", and hit the export.


    a 10 min file is taking 4 hours to render.


    This is on a:


    2012 MacBookPro i7 2.3Ghz, 16 GB 1600 DDR3, SSD disk. - Mac OSX 10.7.5

    and a:

    2011 iMac i7 3.7Ghz, 16 GB 1333 Mhz, 7200 RPM HD - Mac OSX 10.7.5


    The CPU stays at 90% idle the whole time.


    I know this is an old thread, but maybe someone could give me a hand.

    have a look at this post I make a week or so ago on what it takes to max out the cpus and even if that is a good thing...
